"Science is not perfect, but it's far better than intuition."
The quote emphasizes the superiority of scientific methods over intuitive thinking in understanding the world around us. Science is systematically based on empirical evidence, observation, and experimentation, which makes its findings more reliable and less prone to error compared to mere intuition or subjective feelings. This doesn't mean that science is perfect, but it provides a far more accurate and predictable way of understanding the natural world.
"Reality is simply what we agree upon."
This quote by Lawrence M. Krauss emphasizes the social, collective nature of understanding reality. In essence, it suggests that our perception of reality is shaped by shared agreements, theories, or consensus within a particular society or scientific community. It underscores the importance of collaboration, communication, and mutual understanding in constructing our knowledge about the world around us.
"If you want to understand the universe, you have to think in a very unintuitive way."
This quote by Lawrence M. Krauss highlights the often counter-intuitive nature of understanding the universe. Our everyday experiences and intuition are based on our personal interactions with the world around us, but the universe at large operates according to complex physical laws and principles that may not align with our common sense or initial perceptions. To fully grasp the cosmos, one must be open to thinking beyond familiar patterns and conventions, embracing abstract and sometimes seemingly illogical concepts in science and cosmology.
"The notion that physics can only describe the physical world, but not explain why it exists or what it's made of, seems to me to be an unnecessary restriction on our understanding."
This quote by Lawrence M. Krauss suggests a desire for a more expansive view in physics, transcending the traditional boundary between describing 'how' things work and addressing questions like 'why is there something rather than nothing?' or 'what is the universe made of?'. He seems to imply that our understanding of the physical world may be enriched by considering not just its operational aspects but also its fundamental nature and origins.
"String theory, in principle, could explain everything that happens in the universe, if we ever figure out how to calculate anything in it."
The quote suggests that String Theory, a theoretical framework in physics, has the potential to provide an all-encompassing explanation for all phenomena observed in the universe. However, this claim is contingent on our ability to calculate or solve problems within the theory, which currently remains challenging due to its mathematical complexity. Essentially, Krauss is indicating that String Theory could be a unifying principle of physics if we can effectively apply and understand it.
The root cause of the looming energy problem - and the key to easing environmental, economic and religious tensions while improving public health - is to address the unending, and unequal, growth of the human population. And the one proven way to reduce fertility rates is to empower young women by educating them.

No one intuitively understands quantum mechanics because all of our experience involves a world of classical phenomena where, for example, a baseball thrown from pitcher to catcher seems to take just one path, the one described by Newton's laws of motion. Yet at a microscopic level, the universe behaves quite differently.

When considering real-world issues, particularly those that touch on science and technology, it is harder to speak in platitudes or rely purely on emotion or fear. Substance, or its lack, becomes harder to mimic or mask, which is why I wish we had a true televised presidential debate on these subjects.

The Internet is a clear example of how our lives have changed in ways we couldn't have imagined: a distributed information source, which is invisible to everyone, where you can access anything, and it's distributed throughout the whole world. Basically, communication is instantaneous.

Richard Nixon, famously, conducted his foreign policy according to the 'madman theory': he tried to convince enemy leaders that he was irrational and volatile in an attempt to intimidate them. But this was a potentially useful approach to foreign policy only because it was an act.

I am in favor of saying, 'Okay, let's get teams of educators and experts in certain disciplines to say, 'What are the basic things that we think are an essential part of an early education for people?'' Put them together and create, as well as possible, a set of goals and tools to learn those things.

Neutrinos alone, among all the known particles, have ethereal properties that are striking and romantic enough both to have inspired a poem by John Updike and to have sent teams of scientists deep underground for 50 years to build huge science-fiction-like contraptions to unravel their mysteries.

Local order in parts of the universe is always possible at the expense of heat and disorder dissipated to the external environment. The human body is one example: we take in energy from our environment to build up complex molecules that help power our bodies, and, in doing so, we release heat to the world around us.
